The fluid movements of a river, made up of a multitude of different ways of flowing, are transformed into the acoustic interplay of voices bundled in a dynamic stream of language, which in turn is played in the attic of a baroque church. The steam consists of conversations, statements and observations revolving around the moving, constantly changing water surface of a river that responds to all kinds of external influences. A researcher into currents and four actors talk about the water’s flow movements, its permanent, unstoppable motion, its meandering; of how the river reacts to resistances, how it behaves in relation to its banks; of points of contact, eddies; of how the water surface relates to the cosmos and reflects it, and so on. Voices rise and fall and make the entire room vibrate. A choir of four different voices is heard from above at all times: they recite a list of verbs describing all of the river’s different actions. A corresponding video piece features a young man standing behind a closed window; he is visibly moved.
